剔除库尔勒体应变观测资料中地震波、仪器标定及明确原因的干扰数据，计算其应变潮汐因子、高频信息和非潮汐速率，结果显示：O1波、半日波潮汐因子在轮台5.4级、新源—和静交界6.6级两次地震前存在明显的异常反映，潮汐因子曲线形态、周期均发生明显的异常变化，异常结束后2—3个月内发震。总结体应变观测资料的异常特征，可有效捕捉前兆异常变化信息，有助于提高台站的地震短临预报水平。

clear the seismic wave, the instrument calibration and interference data of Korla body strain observation data, calculate the strain tide factor, high frequency information and non-tidal rate, the results indicates that O1 wave, semidiurnal tidal factor exist abnormal obviously reflect before Luntai 5.4, Xinyuan-Hejing border 6.6 earthquakes. tidal factor curve shape, cycle occurred obvious anomaly, then earthquake happened after 2 - 3 months.  summarize the abnormal characteristics of body strain observation data, which can effectively capture the precursor anomaly information, help to improve the short-term earthquake prediction level of station.
